I have a crush on this girl for 4 years. I tried to date her she refused me. Yesterday, I met her in a club we drank a lot. The night is over I offer to get her home, she initially says no but I insist. Then she says OK. I went to her apartment and we fucked. She initially showed some LMR but when I was about to leave she get herself naked and I fucked her.

I am very confused about this. All the night she asked me if I'm fucking someone else and I say: sometimes I do. Then she asks me if she knows the girl. And I say: yes. Then it started to get crazy. She didn't stop questioning me about the girl.

After we fucked she says: so you cheated on X? I didn't reply.

I suspect that she is a serial cheater and she feels good knowing that others cheat.

PS: I lied about fucking someone else. I am actually on a very scarce run with no girls to date. But apparently just giving the impression that I'm fucking someone else got me laid. I am really confused about how girls work. And disappointed.
